How to Say ‘What is it for? / what does it do?’ in Mexican Spanish

¿para qué sirve?

PAH-rah keh SEER-veh

[PAH-rah keh SEER-veh]

💬 Usage Tip: “¿Para qué sirve?” literally “What does it serve for?” = what’s its purpose/function. Great for features and buttons.

🇲🇽 In Mexico: At conferences in Mexico, people may ask this directly. It’s a practical, “show me the value” kind of question.
